Using an electric mixer, cream the butter and peanut butter together in a large bowl until thoroughly mixed and creamy. Add powdered sugar; mix until smooth. Mixture will be thick.
Using a spoon, scoop out mixture and roll/shape into (approx.) 1 inch balls between your hands. Place rolled bon bons onto a wax or parchment paper lined baking sheet. Store in refrigerator to chill for a couple of hours.
Right before the bon bons are done "chilling", prepare chocolate coating mixture to dip them in: Place the chocolate chips and the vegetable shortening in a microwave-safe bowl. Microwave on high for 30 seconds. Remove. Stir chocolate and shortening. Place back in microwave and microwave for 30 additional seconds. Remove and stir. (You do it this way to prevent the chocolate from burning). By now the chocolate and shortening should be completely melted and smooth. If not (some microwave temps vary), put it back in for 15 seconds and stir. Remove from microwave. *Tip: If the chocolate is still too thick for dipping, just add a tiny bit more shortening and microwave for a few seconds.* (If you prefer, you can also prepare the chocolate and shortening in a double-boiler...again...whatever works for you).
Remove bon bons from refrigerator and dip each one completely in melted chocolate. I use a toothpick inserted into bon bons to dip into chocolate, then remove the toothpick and fill in the small hole on top of bon bon with additional chocolate. As each bon bon is dipped, place on wax or parchment paper to allow chocolate time to "harden".
When chilled, place each bon bon in a small paper candy holder, and refrigerate! Enjoy.
